Hierarchical Higher Order sFace Cluster Radiosity for Global Illumination Walkthroughs of Complex Non-Diffuse Environments
We present an algorithm for simulating global illumination in scenes composed of highly tessellated objects with diffuse or moderately glossy reflectance. The solution method is a higher order extension of the face cluster radiosity technique. It combines face clustering, multiresolution visibility, vector radiosity, and higher order bases with a modified progressive shooting iteration to rapid...
متن کاملHierarchical Higher Order Face Cluster Radiosity
We present an algorithm for simulating diffuse interreflection in scenes composed of highly tessellated objects. The method is a higher order extension of the face cluster radiosity technique. It combines face clustering, multiresolution visibility, vector radiosity, and higher order bases with a modified progressive shooting iteration to rapidly produce visually continuous solutions with limit...
متن کاملInteractive Walkthroughs and Higher Order Global Illumination
The subtle lighting effects, which can be simulated by global illumination, are important to make virtual worlds look realistic. Higher order global illumination methods, like Wavelet Radiosity, have proven to be very efficient, but do not directly lead to solutions that can be used by the hardware used to display walkthroughs. In this paper, we discuss methods to efficiently map these higher o...
متن کاملHIRAD: A Hierarchical Higher Order Radiosity Implementation
In this paper we describe our hierarchical higher order radiosity implementation, called HIRAD. We present a number of improvements to the original wavelet radiosity method: We propose new basis functions for (convex) quadrilaterals and for triangles offering finer granularity than the usual product-1D bases, a new refinement criterion for hierarchical refinement and a very general strategy for...
متن کاملDIRmaps : Discretized Incident Radiance Maps for High-Quality Global Illumination Walkthroughs in Complex Environments
Realtime ray tracing and interactive global illumination have recently made significant progress, allowing for ray traced rendering quality even in highly complex scenes. Nevertheless, high-quality global illumination is currently still limited to offline computations, as existing interactive techniques are applicable only to simple scenes, BRDFs, and/or lighting conditions. For realistically c...
